Comments [?]

Function Catalyzes the interconversion between ADP-D-glycero-beta-D-manno-heptose and ADP-L-glycero-beta-D-manno-heptose via an epimerization at carbon 6 of the heptose.
Catalytic activity RHEA:17577: ADP-D-glycero-beta-D-manno-heptose = ADP-L-glycero-beta-D-manno-heptose
EC 5.1.3.20
Cofactor NADP(+)
Note: Binds 1 NADP(+) per subunit.
Pathway Nucleotide-sugar biosynthesis; ADP-L-glycero-beta-D-manno-heptose biosynthesis; ADP-L-glycero-beta-D-manno-heptose from D-glycero-beta-D-manno-heptose 7-phosphate: step 4/4.
Subunit Homopentamer.
Domain Contains a large N-terminal NADP-binding domain, and a smaller C-terminal substrate-binding domain.
Similarity Belongs to the NAD(P)-dependent epimerase/dehydratase family. HldD subfamily.
